A camera is described that includes a first imager and a processor communicatively coupled to the first imager. The first imager captures images of a roadway on which a vehicle is located when operating. The processor, when operating, generates a signal to cause a first hybridized device in the vehicle to project a first patterned light on to an object on the roadway, generates a signal to cause the first imager to capture an image of the first patterned light projected on the object, receives the image from the first imager, and detects the object on the roadway based on the first patterned light captured in the image.

Vehicle camera vision and control system and method

A lighting system for a vehicle is described, which includes a first hybridized device, a second hybridized device and a controller. The first hybridized device includes a first array of light emitting devices that illuminate a roadway on which the vehicle is located when operating. The second hybridized device includes a second array of light emitting devices that illuminate the roadway on which the vehicle is located when operating. The controller is electrically coupled to the first and second hybridized devices. When operating, the controller causes the first hybridized device to selectively project a first patterned light on to an object on the roadway, causes the first hybridized device to selectively project a second patterned light on to the object on the roadway, and causes a first camera to capture an image of the first patterned light projected on the object and the second patterned light projected on the object.

A light-emitting diode (LED) can have a light-emitting surface that can emit emitted light. A filter, disposed on the light-emitting surface, can be at least partially transmissive in a first area and at least partially reflective in a second area. The first area can direct at least some of the emitted light through the filter to form shaped light that extends over an area corresponding to a shape of a static light pattern. The second area can reflect at least some of the emitted light into the LED through the light-emitting surface. A lens can bring the shaped light to a focus that has the shape of the static light pattern. To increase a contrast of the focus, an absorber, disposed on the second area of the filter, can absorb emitted light that is transmitted through the second area of the filter.
